High-Speed Gray Iron Expert | Flat-Top Rigidity | UC5105 Hardened Grade
The Speed Master for Cast Iron
UC5105 Grade (Ultra-Hard CVD): This is Mitsubishi’s hardest grade for **K-class materials**. It features a specialized CVD coating with optimized grain growth control, providing superior resistance to abrasive wear. It is the "Speed Demon" for Gray Cast Iron, allowing you to increase productivity by running at higher surface speeds than standard grades.
CCMW Geometry (Flat-Top Design): Gray cast iron produces fragmented chips that do not require a chipbreaker. The CCMW flat rake face ensures that the cutting edge is backed by the maximum amount of carbide. This "no-chipbreaker" approach prevents crater wear and edge deformation, which are common when using CCMT inserts in high-speed iron applications.
0.8mm Precision Radius: The 08 (1/32") radius is the optimal balance for medium roughing and semi-finishing. It provides high edge strength to survive the initial impact of casting skin while maintaining excellent surface finishes at moderate to high feed rates.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMW120408 | 12.7 mm | 4.76 mm | 0.80 mm |

High-Speed Cutting Parameters
*UC5105 is designed for high-speed stability. It is not recommended for heavy interrupted cuts or low-speed applications.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Cast Iron (FC250/300) | 250 - 600 m/min | 0.15 - 0.45 mm/r | 0.50 - 4.00 mm |
| Hardened Iron / Chilled Iron | 100 - 250 m/min | 0.10 - 0.30 mm/r | 0.50 - 2.50 mm |

Shop SCLCR 12 HoldersPro-Tip: UC5105 vs. UC5115
UC5105: The Wear Resistance Master. Best for continuous, high-speed turning of Gray Iron where tool life at high RPM is the priority.
UC5115: The Toughness Expert. Switch to UC5115 for Ductile Iron (FCD) or for machining parts with boltholes and gaps, as UC5105 is more brittle and may chip under heavy impact.
